About

WHAT IS CRYPTO BLOCKCHAIN

Crypto Blockchain is a blockchain technology developed using advanced cryptographic techniques such as homomorphic encryption and zero-knowledge proofs, as its name suggests.

  • Storage of homomorphically encrypted transaction data in a distributed ledger using an Elliptic Curve-based Homomorphic Cryptosystem (ECHC).
  • Operation of transaction data in an encrypted state without the decryption process.
  • Zero-Knowledge Proof technology zk-FIDNA for transaction validation.

In line with the slogan "Fully Encrypted, Always Secure," we aim to provide a perfect security environment by compactly encrypting transaction data using homomorphic encryption and enabling transactions to be conducted without the need for decryption.

Establishing the Concept of Multi-Blockchain through SubBlockchains.

To study blockchain mathematically, we analyzed and formalized its mathematical properties. Based on this foundation, we developed the concept of SubBlockchains, establishing a framework capable of handling various types of data.

  • TransactChain : A blockchain for storing and processing transaction information.
  • AuthChain : A blockchain for storing and managing data for authentication.
  • NFTChain : A blockchain for issuing and managing NFTs for digital contracts

We integrate various services through SubBlockchains. The personal information wallet, Strongbox, transmits personal data via the AuthChain. Transaction data generated through Remit is stored on the TransactChain, and NFTs for digital contracts are issued through the NFTChain.

TransactChain : A blockchain for storing and processing transaction information

As a subBlockchain for managing transaction data, financial transaction information can be encrypted through homomorphic encryption, allowing for direct computations without the need for decryption, thereby preventing data leakage at its source.

  • Encrypt transaction data using homomorphic encryption for processing directly on ciphertext.
  • Eliminate data leakage risks by removing the need for decryption.
  • Process all operations within ciphertext and perform comparative verification procedures to act as a real ledger.

AuthChain : A blockchain for storing and managing data for authentication

SubBlockchain 2, AuthChain, stores authentication data in an encrypted state on the blockchain, enabling similarity checks to be performed while the data remains encrypted. This allows for authentication based on biometric data, such as fingerprints and signatures, ensuring a secure and privacy-preserving verification process.

  • Store authentication data on the blockchain for verification purposes.
  • Perform authentication through similarity calculations directly on ciphertext.

NFTChain : A blockchain for issuing and managing NFTs for digital contracts

It provides the functionality to issue digital contracts for both financial and non-financial transactions, along with the issuance of NFTs for these digital contracts, ensuring legal ownership rights.

  • Request personal information from the transaction participants via Strongbox when a transaction is initiated.
  • Issue a digital contract for the transaction based on the provided personal information.
  • Mint an NFT for the digital contract and securely store it.

Frequently Asked Questions

Frequently Asked Questions

You can use the Crypto Blockchain wallet through this site, and Remit and Strongbox can be downloaded and used from the designated pages.

No, it isn’t. We have developed a system using blockchain technology to ensure secure transactions, and we are in the process of commercializing this. Please understand clearly that this is different from a coin-based business.

Yes, Crypto Blockchain requires the use of Remit for transactions and Strongbox for digital contracts, making them essential.
